Deployment
GWh / GWBattery capacity in the real world
Stationary storage already online, annual battery additions, and where new capacity is being built.

Track the battery and solar transition as it deploys.
A living view of storage GWh, solar buildout, EV adoption, BESS sectors, and the power mix behind them.
The swarm starts on a rooftop. Start with yours.
Featured · The state of the energy transition
Where battery power stands.
Solar and wind became the cheapest electricity ever built. The new race is storage — and it just went vertical. A data-driven look at where we were, and where we are now.

The Long Sunrise
Half a million years of energy — and the century that changes it. From the first tended fire to terawatt solar, grid batteries, orbital compute, and the work still between us and morning.
Begin in the darkWhat we track
The battery transition needs more than one number.
battery.mom follows the shift from fossil-heavy electricity toward solar, storage, and electrified transport. The useful view is not just product specs. It is deployment, adoption, market readiness, and the power mix around it.
Adoption
Homes / EVs / sitesWho is actually using it
EV uptake, home batteries, shared residential systems, commercial storage, grid projects, and charging hubs.
Energy mix
TWhWhat storage is shifting
Battery deployment shown beside solar, wind, hydro, nuclear, coal, gas, and oil electricity generation.
Readiness
Policy + priceWhether the market can scale
Tariffs, incentives, battery pricing, solar yield, charging density, payback, and source coverage.
Why trust it
Clear data beats confident sales talk.
battery.mom is deliberately plain about uncertainty. Prices change, incentives move, and product claims age. The point is to keep the assumptions visible.
